Porous One‐Dimensional Photonic Crystals Improve the Power‐Conversion Efficiency of Dye‐Sensitized Solar Cells

The solar‐to‐electric power‐conversion efficiency (η) of dye‐sensitized solar cells can be greatly enhanced by integrating a mesoporous, nanoparticle‐based, 1D photonic crystal as a coherent scattering layer in the device. The photogenerated current is greatly improved without altering the open‐circ...

Zusammenfassung:The solar‐to‐electric power‐conversion efficiency (η) of dye‐sensitized solar cells can be greatly enhanced by integrating a mesoporous, nanoparticle‐based, 1D photonic crystal as a coherent scattering layer in the device. The photogenerated current is greatly improved without altering the open‐circuit voltage of the cell, while keeping the transparency of the cell intact. Improved average η values between 15% and 30% are attained.
